What I'm looking for

I'm looking to build scalable backend, cloud, and AI-powered systems where I can contribute to API design, event-driven architecture, and real-world product development while continuing to grow as an engineer.

I've built backend systems at FlyRank AI, including FastAPI/Pydantic CRUD APIs, a Supabase-authenticated service, and a GitHub repository-to-study-notes generator powered by Gemini AI. SQLite caching delivered a 15x speedup for repeat queries, and my case study automation workflow reduced documentation time by 64%.

For a Capital One senior capstone, I coordinated a team integrating GitHub and Jira through an event-driven AWS microservice. I co-led the architecture pivot to AWS-based routing, documented system tradeoffs, and managed stakeholder communication throughout the project.

I'm also building AI and full-stack products with React, FastAPI, TypeScript, Express.js, and TypeORM, while researching procedural texture generation with Perlin noise. As a CodeWizardsHQ instructor, I taught Python backend fundamentals and API design and earned Outstanding Instructor recognition for making system-level concepts clear.
